However, my one shot at it in a 2007 (I think) Z4 (stock) was fairly painful due to the current road conditions - very choppy, very broken pavement. In the Z4 I was dodging giant holes the entire way up and constantly getting my teeth knocked together.

My guess is you could do it, I don't have a ton of experience with lowered cars - I'm assuming you are as low or lower then the Z4.
